Has anyone had issues with their Ridge 4512 binding when lowering the blade?
When lowering the blade, about half way down it binds up and the elevation adjustment wheel barely turns. I can force it and it unbinds itself and will go down. After I raised it all the way then lower it again, it binds up again on the way down. Any suggestions?

Look carefully at the gears underneath the table and clean out all sawdust and stuff. A little grease is supposed to be on the gears. There was a discussion around here about that. Some say grease get’s gunked up with sawdust and you should only use dry lube. Others say they’ve used ordinary grease for years with no issues.

My comments are not specific to your saw. I have a different Ridgid model.

This problem can likely be fixed with a toothbrush. That’s an appropriate tool to get mashed in sawdust out of the gears, and also to apply wax as a lubricant. Wax needs to be reapplied more often than grease.

I have a Ridgid 4512 and have a similar problem. Open the back access door and directly in front you will see the end of the elevator worm gear. There is an E clip and thin washer on the end of the worm gear stopping lowering at the lowest point. For some reason that clip and washer came off on my saw and I could not raise or lower the blade at all. I’ve replaced the clip and washer several times as they continue to come off. The washer is quite thin and Ridgid is no longer supporting it, also I’m in a remote area and the nearest Home Depot or Lowes is an hour away so it is a pain. I had hoped Ridgid would have a solution but they don’t
I have cleaned the worm gear and teeth with brushes and used dry lubricant as there is so much sawdust that I don’t want it to get gunked up by using wet lubricant or grease, as well. If I am careful and don’t try to lower the blade below the table top, this seems to work for me. I have to clean this mechanism often, too
